The LED mine tunnel light is a new generation of semiconductor light-emitting cold light source device, characterized by energy saving, long lifespan, easy maintenance, high brightness, and the ability to focus or disperse light. The concentrated light fixtures have a long irradiation distance, making them particularly suitable for lighting in tunnel chambers, shunting sites, substations, and pump hoist rooms. Below, I will introduce its performance, structure, and usage environment.

Performance and Structure

The explosion-proof LED tunnel light for rock use employs a high-efficiency, energy-saving, and environmentally friendly high-lumen high-power LED as the light source. The LED uses imported high-brightness chips with a light efficiency of up to 100Lm/W. It has strong shock resistance, excellent dustproof performance, low energy consumption, low voltage and current requirements, low heat generation, minimal luminous heat, and does not pose safety hazards, ensuring a high safety factor. LED lighting belongs to solid light sources, with epoxy resin packaging, making the light-emitting part less prone to loosening. Its lifespan can reach 30,000 to 50,000 hours, which is 30 times that of ordinary bulbs, equivalent to three years of continuous lighting.

Continuous use without replacement, maintenance-free. The shell is made of die-cast aluminum, with a surface powder electrostatic spray coating, high-temperature silicone rubber sealing rings, and tempered light-transmitting glass, featuring explosion-proof, waterproof, impact-resistant, and shock-resistant characteristics. The integrated design is unique, aesthetically pleasing, and has good heat dissipation. It has a built-in high-quality switch power supply, with a wide voltage range, low operating temperature, and maintenance-free.

The integrated LED light source is fixed to the aluminum heat sink with screws, using silicone for better thermal conductivity for bonding and packaging. This allows the working heat of the LED light source to be conducted to the shell, increasing air convection cooling, thereby reducing the temperature of the explosion-proof LED tunnel light and the junction temperature of the LED, improving light efficiency and extending the lifespan of the explosion-proof LED tunnel light.

The transparent lampshade and protective cover mainly protect the LED light source from damage due to external impacts. With a protective mesh cover, the transparent lampshade can withstand an impact energy of 4J. The mesh of the protective cover is less than 50mm x 50mm.

Usage Environment:

Environmental humidity: -5C to +40C. Air pressure is 0.8-1.1 x 10'PA, altitude 2000m.

The average relative humidity of the surrounding air is not greater than 95%.

It can be used in places with the risk of gas and coal dust explosions.

In other environments without destructive insulation or steam, the pollution level is grade three.

This concludes my introduction, and I hope it helps everyone understand the LED mine tunnel light.
